How do vbseo rewrites work?

I recently upgraded my server from Apache with Mod_Rewrite to Nginx and php-fpm. I was using the vbseo.com preset for my rewritten forum URLs, which uses regex.

For example:
http://www.domain.com/forums/forumdisplay12803812.php

Was changed to:
http://www.domain.com/forums/f11/

I noticed after upgrading that the above URL broke, which meant visitors couldn't actually navigate to any of the forum sections.

My question is, how does vbseo do its rewrites? Are things like the vbseo.com forum presets done with Mod_Rewrite, or are they all regex? Should I be disabling options like "rewrite forum urls" in vbseocp? Or should regex presets work as-is with Nginx?

I've put together a list of all my rules, including regex. I have found a nginx professional and will be paying them to fix the broken URLs, however I need to know what to tell them to fix.

Finally, do nginx rewrites (e.g. permanent redirects) need to be placed in their own config files, or can I place them in vbseo? (i.e. replace my Mod_Rewrite rules with them)

Perhaps other vbseo customer who've made the switch to nginx would care to share their experiences?

If it helps, I'm running vb 4.1.3, vbseo 3.6 and the latest versions of nginx/php-fpm.

Is anyone able to answer this? Just to clarify, my basic question:

If I convert my rewrite rules to nginx, can they still be placed in the vbseo cp, or should they go in my Nginx vhost.conf file? If they need to be in the Nginx conf file, should I disable rewriting forum URLs, etc. in the vbseo cp? Thanks

Hello Aaron,

Could you please elaborate on what do you mean with "If I convert my rewrite rules to nginx, can they still be placed in the vbseo cp"?.

What rewrite rules are you referring to?.

andres">Andres,

I'm speaking of CRRs.

I see now. You should leave them in the vBSEO CP, as this functionality works in the same way as if you were using Apache.
